You, of course, are kidding about the Segway!
As for the YikeBike, well, I really like the YikeBike. It's too expensive, but hopefully that will change. Some things from the FAQ...
The YikeBike is electronically limited to 25 kph. We'll need a hack for that ASAP.
The YikeBike can comfortably take a rider (and personal effects) weighing up to 100kg. Sorry, no sales in the US, and a shrinking market (punny, huh?) in the UK, Aus and Canada.
